Teen Mom 2 stars Kailyn Lowry and Jenelle Evans are known for butting heads, so when it was revealed that Evans plans to homeschool her 11-year-old stepdaughter, Lowry couldn’t resist weighing in.

Evans, who now uses her married name, Jenelle Eason, announced the homeschooling news in a tweet calling out Lowry’s podcast. This prompted her own estranged mother, Barbara Evans, to call her “dumb as a friggin’ rock,” while Lowry made fun of Evans’s education.

This is so scary. David has isolated Jenelle and now they're isolating Maryssa from normal social interaction? This poor young woman is going to be stuck on the junkyard swamp 24/7 and receiving a halfass education from a junkie who barely made it out of high school!!!
